` To dll whom 'it 'may concern:

Be it known that I, J AMES IV. PmiirioN,

a citizen of the VUnited States of Ameri-a,-

drawing.

residinggat Oil City, in the county of I e- 'naiigb 'and State'of Pennsylvania, have invent'ed certain new and useful Improvements in- Ejectors for Oil-IVells, of which the following is av specification, reference being had therein to the accompanying invention relates to liermetieally sealed casin ,for the purpose of creating a vacuum an suction that will 4convey the fluid 204 p in a continuous stream through a suitable discharge pipe to the top -Another object of my present invention 'i `isfto povide simple and eli'ectual means that occasion requires; furthermore,

may easily secured in anArtesianor eil well, and readily removed therefrom when to provide apparatus that isnot apt to get. out of order or clog.

Heretofoi'e, great diliiculty has been-.ex-'

perienced in providingdevices wherein compressed air is used to .force the fluid from the well, by reason of the extremely high fessure required for the purpose, and it is the aim of the presentinvention to overcome such diiiiciilties by the use of a novel l device that will b e hereinafter more particularl explained and specifically pointed out in the claim.

In describing the invention in detail, reference isuhad to the accompanying drawings,

,the ffrure whereof represents a vertical sectionalview of a. portion of an Artesian well equippedk with my improved device.

In this drawing, the various parts are indicated by reference numerals, as follows is secii'ied a standing valve 6 which is a ilivitiy valve of any suitable construction; e siiid. reducer o is secured by means of ing member,

. certain new and useful improvements in e]ector for flowing screwthreads 7 to a casing S, carry-ing a cap 9, and having foi-ined integral with said cap two screw threaded nipples 'l0 and l1 spaced apart; the 'said nipple"10 being adapted to receive an air pipe 12 extending through the casing head 3, and provided with a coupling 14 into which an air pipe 15 leads from anair compressor, not shown in the drawing. In the said nipple 10 is secured anai'r pressurepipe 1G, extending into the chamber 17. formed by the casing 8, reducer 7 and 'cap 9; this chamber 17 '1s hermetically sealed, the pipe lterminating in a U- shaped portion 1S carrying check valve 19 to which is secured an injector 20, said injector extending into the nipple 11 to which is secured a discharge pipe 21, extending upwardly through the casing head 3. An

jector 20 andthe interior walls of the opening which communicates with the nipple 11, and the discharge pipe 2l.

The operation of my improved device for iowing oil wells is as ollowsz-The force pump being operated, forces air under a high pressure through the pipes 15, 12, 16 and 18,- through the injector 20 into the pipe 21, thereby creating a suction that will open the standing valve (3, permittinn' the liquid to rise into the vacuum charniier 17, and thence through the opening 22 into the d ischarge pipe 21, wherein it willbe carried to la suitable point of discharge/at theupper end of the pipe. lt will be understood that by the use ot' my improved device, a constant flow of the fluid may be produced, but

' that when the air compressor ceases operation, Hic standing valve then will auto'- matically close and prevent any Huid which remains in the vacuum chamber from returning into thewell. It will also be noted that all the part-s 'may be easily taken apar-t and renewed should the occasion require; furthermore that various changes may be made in the details of construction without departing from the general spirit of my invention.

Having fully described my invention, what I claim as 'new and desire to secure by Letters Patent, is

'. In a device of theclass described, a casing comprising spaced upper and lower` caps and an intermediate tubular connectsaid lower cap having an inteannular space 22 is formed between the in-` gral vulve Seat and sind upper cap having l with spliced guide ways, an air-'supply pipe extendilig into Said well Casing' and connected into one of snid n1 ples and projecti'ng through one of said c osure guide Ways,

n discharge pipe extending through said Well cnsmgg and connected into the other of sind nipples and projecting through the other of said guide AWays, a U-shnped pipe having a check valve and connected at one end with the nipple into which the aixheupl ply coupled and With'an ejector nozzle :it

the other end entering the nipple with which the 'discharge pipe is connected.

o In testimony whereof I uliix my signutllre in' the presence of two Witnesses.
